Figure 3 - 42 MLD Snooping Parameters Settings – Edit window
The following parameters may be viewed or modified:
Parameter	Description
VLAN ID	This is the VLAN ID that, along with the VLAN Name, identifies the VLAN for which
	to modify the MLD Snooping Settings.
VLAN Name	This is the VLAN Name that, along with the VLAN ID, identifies the VLAN for which
	to modify the MLD Snooping Settings.
Query Expiry Time	Displays the query expiry time in seconds.
Query Interval (1-65535 sec)	Allows the entry of a value between 1 and 65535 seconds, with a default of 125
	seconds. This specifies the length of time between sending IGMP queries.
Max Response Time	This determines the maximum amount of time in seconds allowed to wait for a
(1-25 sec)	response for MLD port listeners. The Max Response Time field allows an entry
	between 1 and 25 (seconds). Default = 10.
Robustness Value (1-255)	Provides fine-tuning to allow for expected packet loss on a subnet. The user may
	choose a value between 1 and 255 with a default setting of 2. If a subnet is expected
	to be lossy, the user may wish to increase this interval.
Last Listener Query Interval	Specifies the maximum amount of time between group-specific query messages,
(1-25 sec)	including those sent in response to leave group messages. A value between 1 and
	25. The default is 1 second.
Data Driven Group Expiry	Specifies the data driven group expiry, in seconds. The user may specify a time
Time (1-65535)	between 1 and 65535 with a default setting of 260 seconds.
Querier State	The default is Disabled. If the field displays “Disabled”, it will always be in MLD-
	Snooping non-querier state.
Fast Done	Used to enable or disable the fast done state of the switch. This field is disabled by
	default.
State	Used to enable or disable MLD snooping for the specified VLAN. This field is
	Disabled by default.
Report Suppression	Used to enable or disable MLD Snooping report suppression for the specified VLAN.
Data Driven Learning State	If the state is Enabled, it allows the switch to be selected as a MLD Querier (sends
	MLD query packets). It the state is Disabled, then the switch cannot play the role as
	a querier.
Data Driven Learning Aged	Used to Enable or Disable the aging out of MLD Snooping data driven learning for
Out	the specified VLAN.
Version	Used to configure the version of MLD used on switch. The default value is 2.
Querier Role	This read-only field describes the current querier state of the Switch, whether
	Querier, which will send out Multicast Listener Query Messages to links, or Non-
	Querier, which will not send out Multicast Listener Query Messages.
